(Status (or lack thereof) of Ambloctonidae)

I always read that Creodonta is divided up into Hyaenodontidae and Oxyaenidae, with Machaeroidinae orphaned somewhere between the two.  I've never heard of Ambloctonidae.--[[User:Stanton|Stanton]] 13:28, 15 June 2008 (PDT)

:I found Ambloctonidae included in Creodonta in Cope (1876). Despite the age of this source, I haven't been able to find out what has become of this family since. It is worth noting that Cope used a much broader concept of Creodonta than is current, including families such as Mesonychidae and Arctocyonidae (but not, funnily enough, Hyaenodontidae, which was not included in Creodonta until 1909), and Creodonta has since been whittled down by removal of families. It is also worth noting that no-one seems to have properly tested the relationships of Oxyaenidae and Hyaenodontidae, and even as currently understood Creodonta may represent a polyphyletic grouping.--[[User:Christopher|Christopher]] 20:23, 15 June 2008 (PDT)

::According to Wikipedia, Ambloctonidae has been shuffled into Oxyaenidae as the subfamily Ambloctoninae [http://en.wikipedia.org/wiki/Oxyaenidae]. I've always wondered why no one has tried to do something to fix the polyphyletic question of Creodonta: it drives me nuts how they always talk about it, but don't do anything about it.    So, does this mean that Machaeroidinae's (lack of) placement is not so much as it having features of both families as people have been too lazy to find the group's own distinguishing features?--[[User:Stanton|Stanton]] 05:56, 16 June 2008 (PDT)

::And speaking of Ambloctoninae/dae, you have any pictures of the skull or skeleton?--[[User:Stanton|Stanton]] 05:56, 16 June 2008 (PDT)
